What New Nations Were Created After Ww1
Introduction
The end of the First World War in 1918 reshaped the political map of Europe, the Middle East, and parts of Africa and Asia. So the collapse of empires—Austro‑Hungarian, Ottoman, Russian, and German—created a power vacuum that the victorious Allies filled with a series of peace treaties, most famously the Treaty of Versailles. These agreements, together with President Woodrow Wilson’s Four‑Point vision of “self‑determination,” led to the birth of numerous new nations between 1918 and 1922. Understanding which states emerged, why they were created, and how they fit into the post‑war order is essential for grasping the origins of many modern conflicts and the evolution of international law.
The Core Principle: Self‑Determination
Self‑determination became the ideological cornerstone of the post‑war settlement. Wilson’s Fourteen Points (January 1918) proclaimed that “the peoples of the world must be given the opportunity to determine their own political status.” While the principle was applied unevenly—great powers still pursued strategic interests—it provided a legitimizing narrative for carving out new states from the ruins of old empires.
New Nations in Central and Eastern Europe
1. Poland – Re‑established (1918)
After more than a century of partitions among Russia, Prussia, and Austria, Poland declared independence on 11 November 1918. The Treaty of Versailles (1919) and subsequent Polish‑Soviet War (1919‑21) defined its eastern borders, granting it territories such as Galicia, Poznań, and parts of Upper Silesia.
2. Czechoslovakia – Founded (28 October 1918)
Formed from the Czech lands (Bohemia, Moravia, and Silesia) and Slovak territories of the former Austro‑Hungarian Empire, Czechoslovakia combined industrial strength with a sizable agricultural base. Its borders were confirmed by the Treaty of Saint‑Germain‑en‑Laye (1919).
3. Yugoslavia (Kingdom of Serbs, Croats and Slovenes) – Created (1 December 1918)
The unification of the Kingdom of Serbia with the South Slavic territories of the former Austro‑Hungarian Empire (Croatia, Slovenia, Bosnia‑Herzegovina, and Vojvodina) produced a multi‑ethnic state that later became known as Yugoslavia. The 1921 Constitution attempted to balance centralist and federalist pressures.
4. Finland – Declared Independence (6 December 1917) – Recognized (1918)
Although Finland declared independence from Russia before the armistice, its sovereignty was only internationally recognized after the war, especially by the Treaty of Tartu (1920) with Soviet Russia.
5. Estonia, Latvia, and Lithuania – Baltic Independence (1918‑1920)
The three Baltic states seized the moment of Russian weakness to proclaim independence. Their borders were solidified by the Treaties of Tartu (Estonia, 1920), Riga (Latvia, 1920), and the Soviet–Lithuanian Peace Treaty (1920). Each adopted democratic constitutions and pursued land reforms.
6. Austria and Hungary – Successor States (1919)
The Austro‑Hungarian Empire dissolved into two separate republics: Austria, reduced to a landlocked state centered on Vienna, and Hungary, which lost roughly two‑thirds of its pre‑war territory (including Transylvania to Romania, Slovakia to Czechoslovakia, and parts of Croatia to Yugoslavia) under the Treaty of Trianon (4 June 1920).
7. Romania – Greater Romania (1918‑1920)
Romania’s borders expanded dramatically after WWI, incorporating Transylvania, Bukovina, and Bessarabia. The 1920 Treaty of Trianon and the Treaty of Paris (1920) recognized these gains, creating a nation that covered almost three times its pre‑war size.
8. Turkey (Republic of Turkey) – Founded (29 October 1923)
While not a “new” nation in the strict sense, the collapse of the Ottoman Empire and the successful Turkish War of Independence (1919‑1922) led to the abolition of the sultanate and the proclamation of the Republic of Turkey under Mustafa Kemal Atatürk. The Treaty of Lausanne (1923) replaced the Treaty of Sèvres, establishing Turkey’s modern borders.
New Nations in the Middle East
9. Iraq – Mandated Territory (1920) → Kingdom (1932)
The former Ottoman vilayets of Mosul, Baghdad, and Basra were placed under a British Mandate by the League of Nations. In 1921, King Faisal I, a Hashemite prince, was installed, laying the groundwork for an independent kingdom in 1932.
10. Transjordan (now Jordan) – Mandated Territory (1921)
Also a British Mandate, Transjordan was granted semi‑autonomous status under Emir Abdullah I, son of Sharif Hussein of Mecca. It achieved full independence as the Hashemite Kingdom of Jordan in 1946.
11. Syria – French Mandate (1920) → Republic (1946)
The League of Nations assigned the Syrian territories to France. Although French control persisted until after WWII, the State of Syria was proclaimed in 1920, and a constitution was adopted in 1925, marking the first legal framework for an independent Syrian state.
12. Lebanon – French Mandate (1920) → Independence (1943)
Created from the former Ottoman Mount Lebanon Mutasarrifate and surrounding coastal lands, Lebanon was granted a distinct identity under the French Mandate, later achieving independence while preserving a confessional political system.

13. Palestine – British Mandate (1920)
The League of Nations granted Britain the Mandate for Palestine, encompassing modern Israel, the West Bank, Gaza, and Jordan. While not a sovereign nation at the time, the mandate set the stage for later state formation and conflict.
New Nations in Africa and Asia
14. Armenian Republic (First Republic of Armenia) – Declared (28 May 1918) – Recognized (1920)
Following the Russian Revolution and Ottoman collapse, Armenians proclaimed independence. The Treaty of Sèvres (1920) initially recognized its borders, but the subsequent Turkish‑Armenian War and Soviet annexation in 1920 ended its brief existence.
15. Azerbaijan Democratic Republic – Declared (28 May 1918) – Ended (1920)
Like Armenia, Azerbaijan emerged from the Russian Empire’s disintegration. It enjoyed a short period of independence before Soviet forces incorporated it into the USSR in April 1920.
16. Georgia (Democratic Republic of Georgia) – Declared (26 May 1918) – Ended (1921)
Georgia proclaimed independence amid the chaos of the Russian Civil War. It pursued land reforms and democratic institutions until the Red Army occupied it in 1921.
17. Czechoslovak‑controlled Carpathian Ruthenia – Joined Czechoslovakia (1919)
While not a fully independent state, Carpathian Ruthenia (now part of Ukraine) was granted autonomy within Czechoslovakia, reflecting the Allies’ attempt to respect ethnic minorities.
18. Territorial Adjustments in the Balkans – Albania, Bulgaria, and others
Albania, already independent since 1912, saw its borders solidified by the 1921 Treaty of Tirana. Bulgaria, a defeated Central Power, lost territories (Western Thrace to Greece, parts of Macedonia to Yugoslavia) under the Treaty of Neuilly (1919), but remained a sovereign kingdom.
The Role of International Organizations
The League of Nations, founded in 1920, became the legal arena where many of these new states sought recognition and where mandates were administered. Although the League ultimately failed to prevent another world war, its framework introduced concepts—collective security, minority rights, and international arbitration—that influenced later institutions such as the United Nations.
Why Some Proposed Nations Did Not Materialize
- Economic Viability: Small ethnic enclaves (e.g., proposed Baltic German state) lacked the economic base to survive.
- Great Power Interests: France secured a security corridor in the Rhineland; Britain prioritized control over strategic waterways in the Middle East.
- Ethnic Complexity: Multi‑ethnic regions like the Balkans and the former Ottoman lands proved difficult to divide cleanly, leading to mixed‑population states that later experienced internal tensions.
Frequently Asked Questions
Q1. How many countries were created directly because of WWI?
Answer: Roughly 20‑25 new or re‑established states emerged between 1918 and 1923, ranging from fully independent nations (Poland, Czechoslovakia) to mandated territories that later became sovereign (Iraq, Jordan).
Q2. Did the Treaty of Versailles create all these nations?
Answer: No. While Versailles dealt primarily with Germany and its colonies, other treaties—Saint‑Germain‑en‑Laye (Czechoslovakia), Trianon (Hungary), Sèvres/Lausanne (Turkey), and the League of Nations mandates—handled most of the territorial re‑arrangements.
Q3. Were any of the new states short‑lived?
Answer: Yes. The First Republics of Armenia, Azerbaijan, and Georgia existed only for a few years before Soviet annexation. Similarly, the Kingdom of Yugoslavia faced internal ethnic strife that eventually led to its breakup after WWII.
Q4. How did the principle of self‑determination affect colonial territories?
Answer: The principle was largely applied to European lands; colonial peoples received little direct benefit. Mandates were presented as “trusteeship” rather than true independence, delaying decolonization for several decades.
Q5. What legacy did the post‑WWI borders leave for the 20th century?
Answer: Many of today’s border disputes—Poland‑Ukraine, Greece‑Turkey, Israel‑Palestine, and the Balkans—trace back to the settlements of the 1919‑1923 peace conferences. The artificial nature of some borders sowed the seeds for later conflicts.
Conclusion
The geopolitical landscape after the First World War was a mosaic of newly forged nations, each born from the ruins of collapsed empires and the idealistic, yet pragmatic, application of self‑determination. In real terms, while some of these states—Poland, Czechoslovakia, the Baltic republics—managed to consolidate and thrive, others were short‑lived or plagued by internal divisions that foreshadowed later turmoil. In practice, the treaties that created them not only redrew maps but also introduced legal and diplomatic frameworks that still influence international relations today. Understanding the origins of these post‑war nations is essential for anyone seeking to grasp the complex tapestry of modern European, Middle Eastern, and Eurasian politics.
